适用场景

  • ONTAP 9.  
  • CIFS
  • ODX

问题解答

  • 无中断运行。  现有 CIFS会话 受影响。
  • 禁用ODX后、影响是为所有 未来 会话禁用ODX。
    • 与其他CIFS选项一样、ODX部分在树连接中协商、并 与会话保持一致、直到断开连接为止
    • 因此、禁用 ODX 不会影响现有会话、但 新会话不会看到执行此操作的选项、并且 不再使用ODX
  • 如果ODX已禁用、则启用ODX也不会产生任何影响。  它仅在 新的 CIFS会话上启用。

  • 然后我们设置...
    • Cluster1::> cifs options modify -vserver <vserver_name> -is-copy-offload-direct-copy-enabled false
  • 已验证此副本仍在使用ODX。
